T 0 all whom it may concern Be it known that I, WILSON T. ROBBINS, a citizen of the United States, residing at 256 Reed Ave, Salt Lake City in the county of Salt Lake and State of Tltah, have invented certain new and' useful Improvements in Bottle-Capping Machines, of which the following is, a specification, reference being had to the accompanying drawings.

This invention relates to an improved bottle capping machine and has for its object to provide a device of this kind including means for capping bottles of diflerent types and sizes.

A further object is to provide a very simple, eflicient and practical device of this kind which is capable of being cheaply made, and sold at a reasonable profit.

A further object of the invention is the provision of means for placing the cap on the bottle, .and also means for releasing the bottle from the capper after the cap has been crimped on the bottle.

A further object is to provide an improved bottle capping machine, which is easy to operate and which requires a very light pressure on the operating means, such as a lever, in order to easily place the cap on the bottle.

The invention further aims to provide a machine which is light in weight and which is strong and durable-and is so constructed as to avoid all danger of breakage. I

While the design and construction at present illustrated and set forth is deemed preferable, it is obviousthat as a result of a reduction of the invention to a morejprac after set forth, shown in the drawingsfand claimed.

In the drawings:

Figure 1 is a view in perspective of the improved bottle capping machine constructed in accordance with the invention} Fig. 2 is a vertical sectional view through the same; and

base, and rising upwardly from one end thereof is an upright 2, there being braces 3 between the upright and the base 1, thereby insuring rigidity between the upright and the base.

The upper sides of the upright have vertical slots 4. An elongated capper head 5, which is rectangular in cross section, is fitted between the sides of the upright, which is likewise constructed rectangular. A bolt 6 extends transversely through the head 5 and through the vertical slots 4 to hold the head in different adjusted positions on the upright. Projecting laterally from the head substantially midway its length is a boss 7 having a guide opening 8. Extending downwardly and laterally from the lower end of the head is a projection 9 terminating in a lateral'part 10, provided with a guide opening 11.

A tubular member 12 is mounted in the guide (openings 8 and 11, and attached to the lower end of the tubular member 12 in any suitable mnaner, for instance by means of threads 13,'though not necessarily, 1s a capping (cylinder 14:. The interior of the lower portion of the capping cylinder is counterbored as shown thereby providing a shoulder 15 on the interior of the cylinder.

A piston 16 is guided in the counterbored portion of the lower part of the cylinder, and constitutes a bottle cap placing member. for placing the cap upon the mouth end of the bottle, which is indicated at 17. The piston or cap placing-member has a plunger rod or stem 18 extending telescopically into the tubular member 12. The lowerend of the plunger or stem 18 is connected in any suitable manner, preferably by threads 19, to-the piston 16. The upper end of-the stem or plunger has a slot 20, through which a transverse pin 21 extends. This pin is fixed transversely of the tubular member 12, by means of its head 22 and a nut- 23. The plunger or stem has limited movement, owing to the opposite ends of-the slot 20 contacting with the pin 21.

mounted at 28 to the capper head 5. The

upper end of the plunger is pivotally mounted between the sides of the lever 27,

Y there being a pivot pin 30 extending through the sides and the lever 27, whereby as the lever is raised or lowered, the capping cylinder 14 is correspondingly moved.

The bottle to be capped is placed upon the base 1 and the cappmg head 5 is adjuster] according to the height of the bottle to be capped, for it is obvious that the sleeve or capping head may be adjusted in different positions for capping bottles of different heights. The bottle-is arranged in position axially with the capping cylinder, and the cap to'befitted to the mouth end of the bottle is placed upon the mouth end of the bottle, and subsequently the lever 27 is lowered, in which case the cylinder is positioned adjacent the cap which is in the form of a disk. A further movement of the lever causes the capping cylinder to move downwardly over the mouth end of thebottle, the cap being forced upwardly into the capping cylinder, owing to its marginal port1on being bent down around the bead of the mouth end of the bottle. During this op-' eration of the capping cylinder, the piston 16 is forced upwardly until it contacts with the shoulder 15. After the cap has been crimped, the lever 27 is raised. A the capping cylinder moves upwardly the piston moves downwardly under the action of the spring 25 thereby removing the mouth end of the bottle and the cap. The bottle is removed, and another bottle is placed in position and the operations previously stated alre then repeated for capping the next'bott e. v

The opposing side faces of the capper head 5 are rovided with grooves 5 for the receptiono the opposite sides of the upper portion of the upright to prevent ivotal movement of the head on the pin 6. he up right 2 is constructed from a single piece of sheet meta'l,'bent to form the double-sided upper portion of the standard, and the lower parts of the sides of the upper portion of the standard diverge downwardly and are connected to the base 1. Where the diverging portions merge downwardly from the opposite sides of the upper portion of nterposed between the 7 the upright a spacing block 5" is secured by the pin 5, thereby holding the opposite sides'of the upright rigid.

The invention having been set forth what i claimed as new and useful is 1. In a bottle capping machine, a frame having an upright provided with an elongated guide loop, a capping head having vertical channels on its outer side faces, in which the sides of the guide loop engage, the sides of the guide loop having slots, means passing. through the head and through the elongated slots for holding the sides of the loop in engagement with the channels, whereby the capping head may have vertical movements, a lever pivoted on the head, a reciprocating capping cylinder, a tubular shank connected thereto and mounted in guides of the head, and in turn pivotally connected to the lever, and means mounted in the capping cylinder for removing the mouth end of thebottle as the cylinder is raised.

2. In a bottle capping machine, a frame including an upright having a looped end comprising-parallel sides, said sides having vertical slots, a capping head having vertical parallel channels on its outer side faces receiving the sides of the loop, means extending through the head and engaging the slots'to hold the sides of the loop in the channels, whereby the head may be guided 1 during its adjustment, a lever pivoted on the head, the head having guides, a capping cylinder, a connector coupling the lever and the cylinder, a spring ten'sioned plunger in the cylinder for removing the mouth end of the bottle when the cylinder is raised, said plunger having means guided and spaced within and loosely joined to the connector for retaining the plunger in a position in the cylinder and preventing it from binding.

3. In a bottle capping machine, a frame including an upright provided with a loop having parallel sides, a capping head having opposite parallel guides operatively receiving the parallel sides, means removably engaged through the parallel sides and said head co5perativelyconnecting the aforesaid parts, whereby the head may be adjusted, a 115 lever operatively mounted on the head, a capping cylinder operatively mounted on the head to have relative reciprocating movements, said cylinder including a shank in guides of the head and in turn operatively 120 connected to the lever, and means operatively mounted in the capping cylinder for relative movement with respect thereto for removing the mouth end of the bottle after the cylinder is raised.

4. In a, bottle capping machine, a frame including an upright provided with parallel sides, a capping head having guide channels in its opposite sides, operatively engaging the parallel sides, thereby guiding 130 said head, means passing through the sides tively connected to the lever, and means opand through the 'head for holding the aforeerativel connected to the cylinder and mov- 10 said parts relatively connected, whereby the able re atively thereto for removing the head may be adjusted for capping a bottle, mouth end of the bottle as thecylinder is a lever operatively connected to the head, raised.
